Background Keratoconus is a chronic degenerative disorder of the cornea characterized by thinning and cone-shaped protrusions. Although genetic factors play a key role in keratoconus development, the etiology is still under investigation.

Prevalence of keratoconus in persons with Down syndrome: a review
Purpose Keratoconus is a vision-threatening condition, and there is a need for knowledge about the occurrence in subgroups of the population. The progression of the disease can be effectively stopped, and vision may be restored, if keratoconus is ...

Pediatric keratoconus - Current perspectives and clinical challenges
Keratoconus is an ectatic corneal disease characterized by progressive stromal thinning, irregular astigmatism, and defective vision. It can be unilateral or bilateral with asymmetric presentation. It starts at puberty and either progresses rapidly to an

Corneal stromal demarcation line after collagen cross-linking in corneal ectatic diseases: a review of the literature [PDF]
Collagen cross-linking (CXL) is a relatively new conservative approach for progressive corneal ectasia, which is able to strengthen corneal tissue reforming new covalent bonds.

Keratoconus is a bilateral disorder of corneal shape which may be sporadic or genetically determined. Early corneal thinning suggests that a functional loss of structural elements is a primary event in the disease. Tensile strength of the cornea is reduced and is expressed by signs of rupture and scarring in Bowman's layer, scarring in the substantia ...

Advance in Keratoconus Biomechanics
Keratoconus is a bilateral asymmetric corneal dilatation disease characterized by localized thinning and increased curvature of cornea. The alteration of the mechanical properties occurs earlier than morphological change owing to corneal structure ...

Analysis of the pathogenic factors and management of dry eye in ocular surface disorders [PDF]
The tear film represents the interface between the eye and the environment. The alteration of the delicate balance that regulates the secretion and distribution of the tear film determines the dry eye (DE) syndrome. Despite having a multifactorial origin,
